Using phosphoryl chloride as catalyst, 5,6-O-isopropylidene ascorbic acid was prepared by the reaction of Vc and acetone, then the product was treated with phosphoryl chloride to produce Magnesium L-ascorbate-2-phosphate.

The refined konjac meal was used as the carrier, loading sodium diacetate and Vc to produce the rice biological antistaling agent.

The effects of ozone treatment on Vc and reducing sugar were evaluated in this paper.

Four lipids with different melting point were chosen to encapsulate the ascorbic acid which has shown the influence on dough's rheological property and bread quality.

In this experiment, we use ascorbic acid and palmitate ethylester as reactant, H2SO4 as catalyst to synthesis L-ascorbic palmitate by ester exchange method.

In this experiment , ascorbic acid and palmitate etbylester were used as reactants,and H2SO4 as catalyst to synthesize L-ascorbic palmitate by ester exchange method .
